Cambridge Audio Releases CXA81 Mk II Integrated Stereo Amplifier

Includes the new ESS ES9018K2M SABRE32 DAC for reference-level digital-to-analog conversion.

Cambridge Audio has announced the CXA81 Mk II integrated stereo amplifier, upgrading the CXA81. Further enhancing CXA81’s sonic performance, Cambridge’s engineering maestros have re-tuned and greatly refined the sound for the CXA81 Mk II — in the process introducing ten new premium components to the circuitry and improving the signal path. The result is even greater clarity and musicality.

The classic combination of Class AB amplification and a chunky toroidal transformer offers superb musical detail with power to drive even demanding speakers. A mighty 80 watts per channel gives it complete authority over the music.

RCA and XLR inputs for analog sources are complemented by TOSLINK, Coaxial, and USB Audio digital connections. Bluetooth aptX HD is also built in for high-quality wireless listening, making it simple to connect a Cambridge Audio Alva turntable, for instance.
